I bought a new fuel pump for my 1994 Integra. When the car gets HOT the car turns-over for 5-10 seconds before it starts. I replaced the fuel pump relay and the problem persists and now I get a lound noise coming from my new fuel pump. What's the problem? Do you have to lower the gas tank to take out the fuel pump? Please advise on what I should do and what I have to do yo replace the fuel pump. Thanks! LEW
